Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] During specific implementation: if figure 1As shown, a bolt device includes a vertically arranged bolt body 1, and two or more bolt support structures are arranged at intervals along the axial direction of the bolt body; the bolt support structure includes a The sleeve 2 of the anchor rod body is provided with a position-limiting structure between the sleeve and the anchor rod body to limit the axial movement of the sleeve along the anchor rod body; on the circumferential surface of the sleeve, three or more A support rod 3 arranged horizontally; a sleeve 4 is slidably sleeved on the support rod, and a transverse thrust mechanism is arranged between the sleeve and the sleeve. The force end of the transverse thrust mechanism is connected with the sleeve and can drive the sleeve along the The support rod moves outward in the axial direction; a sleeve li...

Abstract

The invention discloses an anchor rod device which comprises a vertical anchor rod body. Two or more anchor rod supporting structures are arranged in the axial direction of the anchor rod body at intervals. Each anchor rod supporting structure comprises a sleeve sleeving the anchor rod body, wherein a limiting structure for limiting the sleeve to move in the axial direction of the anchor rod bodyis arranged between the sleeve and the anchor rod body, and three or more horizontal supporting rods are connected with the circumferential surface of the sleeve. The anchor rod device is characterized in that the supporting rods are slidingly sleeved with the sleeves, transverse thrust mechanisms are arranged between the sleeves, the force exerting ends of the transverse thrust mechanisms are connected with the sleeves and can drive the sleeves to move outwards in the axial direction of the supporting rods, and the sleeve limiting structures are arranged between the sleeves and the supportingrods and can prevent the sleeves from being disengaged from the outer ends of the supporting rods. The anchor rod device has the advantages of being more convenient to use, higher in adaptability andcapable of improving the anchor rod installation quality.

Description

technical field [0001] The invention relates to the technical field of construction; in particular, it relates to a bolt device. Background technique [0002] Bolt and shotcrete support measures for supporting surrounding rock with bolts and shotcrete have been widely used since the 1960s. Anchor rods, shotcrete and surrounding rock together form a load-bearing structure, which can effectively limit the free development of surrounding rock deformation, adjust the stress distribution of surrounding rock, and prevent the rock mass from loosening and falling. It can be used as temporary support during construction, and in some cases, it can be used without permanent support or lining. According to the geological conditions of the surrounding rock, various support forms can be used: ①Anchor bolts are used alone, generally only for local parts; The top arch and side wall of the cavern; ④Anchor rod and sprayed concrete, adding single or double-layer steel mesh can improve the te...
